XML Security Overview

Adrian Lane · September 15, 2009

As part of the interview process for our intern program, we asked candidates to prepare a couple slides and write a short blog post on a technical subject. Rich and I debated different subjects for the candidates to research and report on, but we both chose “XML Security”. It is a very broad subject that gave the candidates some latitude, and there was not too much research out there to read up on. It also happened to be a subject that neither Rich nor I had researched prior to the interviews.…

Google and Micropayment

For a security blog, this is a little off topic. I recommend you stop reading if you consider my fascination with payment processing tiresome.

New Definition: Vendor Myopia

Vendor Myopia (ven.dor my.o.pi.a) n.

  • Inability to perceive competitive objects clearly.

  • Abnormality in judgement resulting from drinking one’s own kool-aid.

Continuing our seemingly endless series on “trusted” sites that are compromised and then used to attack visitors, this week’s parasitic host is the venerable New York Times.

Friday Summary - September 11, 2009

Adrian Lane · September 11, 2009

We announced the launch of the Contributing Analyst and Intern program earlier this week, with David Mortman and David Meier filling these respective roles. I think the very first Securosis blog comment I read was from Windexh8r (Meier), and Chris Hoff introduced me to David Mortman a couple years ago at RSA, so I am fortunately familiar with both our new team members. We are lucky to have people with such solid backgrounds wanting to join our open source research firm. Rich and I put up a blog…

Rich and I are going to be at TechTarget’s Washington DC Data Protection Decisions Seminar on September 15th. We will be presenting on the following subjects:

Format and Datatype Preserving Encryption

Adrian Lane · September 9, 2009

That ‘pop’ you heard was my head exploding after trying to come to terms with this proof on why Format Preserving Encryption (FPE) variants are no less secure than AES. I admitted defeat many years ago as a cryptanalyst because, quite frankly, my math skills are nowhere near good enough. I must rely on the experts in this field to validate this claim. Still, I am interested in FPE because it was touted as a way to save all sorts of time and money with database encryption as, unlike other…

Say Hello to the New (Old) Guys

Rich · September 9, 2009

A little over a month ago we decided to try opening up an intern and Contributing Analyst program. Somewhat to our surprise, we ended up with a bunch of competitive submissions, and we’ve been spending the past few weeks performing interviews and running candidates through the ringer. We got all mean and even made them present some research on a nebulous topic, just to see what they’d come up with.

Last week I started talking about data security in the cloud, and I referred back to our Data Security Lifecycle from back in 2007. Over the next couple of weeks I’m going to walk through the cycle and adapt the controls for cloud computing. After that, I will dig in deep on implementation options for each of the potential controls. I’m hoping this will give you a combination of practical advice you can implement today, along with a taste of potential options that may develop down the road.

Critical MS Vulnerabilities - September 2009

Adrian Lane · September 8, 2009

Got an IM from Rich today: “nasty windows flaw out there – worst in a long time”. I looked over the Microsoft September Security Bulletin and what was posted this morning on their Security Research and Defense blog, and it was clear he is right.
